Mary’s life was one filled with joys, sorrows, virtues and love for God. The Scriptures tells us that she kept all these things in her heart.
The shepherds go to Bethlehem and find Mary and Joseph and the baby lying in a manger. They tell Mary and Joseph of the message they received from the angel. The infant’s parents are amazed at what they are being told.
And Mary kept all these things, reflecting on them in her heart. (Lk 2: 19)
Then, after having looked for Jesus for three days, the parents of this child find him in the Temple. They do not understand when he asks them why they were looking for him since he must be in his Father’s house.
He went down with them and came to Nazareth, and was obedient to them; and his mother kept all these things in her heart. (Lk 2: 51)
The sayings and doings of Jesus were pondered in her heart. There in her heart she would ponder over them in order to live by them.
One of the features of the First Saturday's Devotion that was popularized after Our Lady appeared at Fatima is to keep Mary company for 15 minutes, meditating on the Mysteries of the Rosary. This can be done by reading the Scriptures that are relevant to the mysteries or by a simple meditation.
Devotion to the Immaculate Heart of Mary comprises a devotion to her physical heart and to her interior life. We can imitate Mary and ponder all these things in our heart. Not only the things in the Scriptures but also all those ways that God is speaking to us each day and the things He is doing in our lives.
As aspiring contemplatives we can also imitate Mary's love for God, she is a model for us of virtues: particularly humility, gratitude, obedience and adoration.
